Burford Capital filed a petition for certiorari with the U.S. Supreme Court on September 30, the final day of the deadline, seeking to overturn the Second Circuit’s March ruling that voided a $16.1 billion judgment against Argentina. The move represents the litigation funder’s last available avenue in U.S. courts after exhausting appellate remedies in New York, while Burford simultaneously pursues a separate claim through the World Bank’s ICSID arbitration system.
